The document describes an OPENi Hackathon held in Athens on September 12-13, 2014. Developers were invited to create applications that utilize the OPENi architecture, giving users control over their personal data. Four teams participated - Heisenberg, The Scouts, DANBOT, and Astrahan. Heisenberg created a news recommendation mobile app. The Scouts created Gorilist, a task management app with sharing. DANBOT created a user dashboard. Astrahan created FileSync to aggregate files from cloud services and upload to an OPENi cloudlet. In the end, all teams demonstrated their projects.
